Hello, we have made a 2 layer board for a STM32f103, and apparently it works fine but we get a random resets now and then. When that occurs there is a 1 in the Bit 27 PORRSTF: POR/PDR reset flag and Bit 26 PINRSTF: PIN reset flag of the Control/statu...
I have a NUCELO-L433RC-P dev board that was working fine for several days but is no longer visible in Win 10 Device Manager. STLinkUpgrade and STM32CubeProgrammer do not find my ST-LINK. STM32CubeIDE gives the error "Error in initializing ST-LINK d...
I am doing a barebones uart demo on NUCLEO-F303K8. I am using uart 2 through the vcp (stlink virtual com port).I see my transmit working. But I have nothing on receive. I have attached my project. Its done in STM32CubeIDE.Here is the main separately/...
I am facing a problem after I finish the debug session. Once I try to reset the cpu via the reset button or manually resetting the CPU via the ST-Link Utility the program does not start. The only way to start the program again is to click agian the d...
I've been having trouble connecting my board through the STM IDE. I've decided that I want to in a sense 'factory reset' the board. Would a full chip erase do this or would it ruin my board?
I am using STm32 nucleo -32 F303K8 board. I see it has the ability to re-route uart2 to st-link to give a virtual com port. However, I see nothing on it. How do I validate the vcom port on linux cube ide? Is there a demo code?
Hello: I have an stm32h753 eval2 board. I recently purchased an stlink-v3set. Connecting to board using CN9, everything works: programming, CPU information, memory dump, etc. However, embedded instrumentation shows that uart1 is asserting a tx empty ...
I've made a custom design of a board with an STM32F070C6B6. When powering on the board and connecting a genuine ST-LINK v2 programmer, the connection fails halfway through the setup.What i've tried (i'm on linux):1) Via STM32CubeProgrammer:Connect un...
Hi, I'm trying to program my 32L0538DISCOVERY board using the STM32CubeIDE but after trying to upload to it it says that: and offers me to update the st link firmware with st link upgrade so it fin'd it there and everything but when I hit the "Open ...
